Traffic estimation and prediction system

Traffic estimation and prediction systems ( TrEPS ) have the potential to improve traffic conditions and reduce travel delays by facilitating better utilization of available capacity. These systems exploit currently available and emerging computer, communication, and control technologies to monitor, manage, and control the transportation system. They also provide various levels of traffic information and trip advisory to system users, including many ITS service providers, so that travelers can make timely and informed travel decisions.

Need for TrEPS

The success of ITS technology deployments is heavily dependent on the availability of timely and accurate estimates of prevailing and emerging traffic conditions. As such, there is a strong need for a traffic prediction system. The needed system is to please use advanced traffic models to analyze data, Especially real-time traffic data, from different sources to estimate and predict traffic conditions na That proactive Advanced Traffic Management Systems(ATMS) and Advanced Traveler Information Systems (ATIS) strategies can be ………………….



In the United States, the FHWA R & D initiated a Dynamic Traffic Assignment (DTA) research project in 1994 to meet the need for a traffic prediction system. The objective of this research is hand to Develop a deployable real-time Traffic Estimation and Prediction System (Treps) to meet the information need in the ITS context. In October 1995 two parallel research contracts Were Awarded to Massachusetts Institute of Technology (MIT) and the University of Texas at Austin (UTX) with a follow-up development and media at the University of Maryland (UMD) respectivement. Each team was required to develop a prototype of TrEPS demonstrating its potential for real-time application capability. After three years of intensive R & D efforts, two prototype TrEPS were developed. The two prototype TrEPS developed by MIT and UTX / UMD are named DynaMIT -R and DYNASMART -X, respectively. Both systems are simulation-based DTA system.


In France, the National Center for Traffic Information (CNIR), coordinators and monitors of the regional traffic and coordination centers (CRICRs). It publishes its website at and is widely referred to in radio and television broadcasts. The advice of “Bison Futé” as the service is called is well known and has been in place for several decades.


In China, Xi’an Jiaotong University (XJTU) initiated a similar simulation-based DTA research project in 2000 with a follow-up development and support at the Shandong Academy of Sciences after 2004. Dr. Yong Lin is the project leader and Houbing Song Is the earliest project member. After six years of intense R & D efforts, one prototype TrEPS was developed in 2006. The overall prototype TrEPS developed by Dr. Lin and his team has more than 20 members is named DynaCHINA (Dynamic Consistent Hybrid Information Based on Network Assignment).


Singapore Implemented the first practical implementation of congestion pricing in the world in 1975, the Singapore’s Area Licensing Scheme . [1] [2] Thanks to technological advances in electronic toll collection , detection, and video surveillance, Singapore upgraded ict system in 1998. [3] (see Singapore’s Electronic Road Pricing )

Scalable Urban Traffic Control

Scalable URban TRAffic Control [1] (SURTRAC) is an adaptive traffic control system developed by researchers at the Robotics Institute , Carnegie Mellon University . SURTRAC dynamically optimizes the control of traffic signalsto Improve traffic flow for urban Both grids and corridors; optimization goals include less waiting, reduced traffic congestion , go short trips, and less pollution. The core control engine combines schedule-driven intersection control (SchIC) [2] with decentralized coordination mechanisms. [3] Since June 2012, A pilot implementation of the SURTRAC system [4] has been deployed on nine intersections in the East Liberty neighborhood of Pittsburgh , Pennsylvania . [5]SURTRAC has been reduced to an average of 40%. [6] [4] A second phase of the pilot program for the Bakery Square district has been running since October 2013. [7]


The SURTRAC system design has three characteristics. Citation needed ] First, decision making in SURTRAC proceeds in a decentralized manner. Decentralized control of individual intersections allows greater responsiveness to local real-time traffic conditions. Decentralization facilitates scalability by allowing the incremental addition of controlled intersections over time with little change to the existing adaptive network. It also reduces the possibility of a centralized computational bottleneck and avoids a single point of failure in the system.

A second characteristic of the SURTRAC design is an emphasis on real-time responsiveness to changing traffic conditions. SURTRAC Adopts the real-time view of prior model-based control methods intersection [8] qui attempt to compute intersection control Plans That optimize traffic actual inflows. By reformulating the optimization problem as a single engine scheduling problem, the core optimization algorithm, termed a schedule-driven intersection control algorithm, [2] is reliable to compute optimized intersection control planes over an extended horizon was second-by-second basis.

A third characteristic of the SURTRAC design is to manage urban (grid-like) road networks, Where there are multiple (Typically competing) dominating flows That shift dynamically through the day, and Where specific dominant flow can not be Predetermined (as in arterial or major Crossroad applications). The intersection controllers. The combination of competing dominant flows and densely spaced intersections presents a challenge for all adaptive traffic control systems. SURTRAC determines dominant flows dynamically by continually communicating projected outflows to downstream neighbors.


The SURTRAC system uses closed-circuit television cameras to sense traffic conditions. [9] Surveillance of public places with CCTV networks has been criticized as an enabling totalitarian forms of government by undermining people’s ability to move about anonymously . Images Gathered by CCTV cameras Can Be Analyzed by automatic number plate recognition software, Permitting fully automated tracking of vehicles by the license plates (number plates) They carry. Similarly, facial sensors can be analyzed to determine whether or not they are the same.

It has been suggested that the benefits of traffic optimization have never been scientifically justified. It inherently favors motorized traffic over alternate modes such as pedestrians, bicyclists, and transit users. [10] [11] It is suggested that an alternate approach could involve traffic calming , and a conceptual focus on the movement of people and goods rather than vehicles.

The WATERWAY system is designed to provide a warning signal that will not cause a warning signal. WALK signal, or else the pedestrian will be given a continuous “DO NOT WALK” signal, despite having a green light. Pedestrians are unlikely to ever reach an intersection that has already had a walk. This results in the same intersection, essentially making pedestrians second-class citizens of the streets. Also, many pedestrians are unaware that pushing the button is mandatory in order to receive a walk, and are confused when an entire light cycle occurs without ever being allowed to cross.

Because they require a continuous supply of electricity, automatic traffic signals are not suitable for use in places where the electric supply is sporadic or nonexistent. For example, traffic in Pyongyang, North Korea is guided by government workers who stand in the intersections under umbrellas. [12] [13]

When drivers become accustomed to automated traffic signals, they may forget how to properly yield the right of way, so that when the electric supply is interrupted, as when a disaster occurs, the traffic has never been used . [14] [ original research? ] This effect Could conceivably delay evacuation or Impede the movement of emergency vehicles.

The introduction of traffic signals and associated laws may undermine democracy by means of citizens to reflexively obey the signal lights. [15] [16] [ original research? ]

Roundabouts are an alternative to signaling systems. At a roundabout, motor traffic may not be able to come to a stop (so that drivers’ time and fuel may be saved), and crossing for pedestrians may be easier. Studies of intersections converted to roundabouts have found reductions in the frequency and severity of accidents. [17] However, these benefits may not be realized if a roundabout is poorly designed. Roundabouts typically require a concave demolition of adjacent structures, so doing such conversions in heavily built-up areas.
